Much better than I had expected
I saw the negative reviews but because when I was a kid I used to dream about giant vehicles the size of small cities battling each other (I've never read the source novels so I'm sure I'm not the only one who had these thoughts) so I wanted to see this film.
Just saw it for the first time at home -- much better than the reviews let on IMHO. Sure the film isn't another "Parasite" but the main thing is that the world is really imagined and visualized well - the big budget really shows up on screen. That's what sold it for me. I thought the leads were good and there was plenty of variation in the film to keep me entertained and drawn in. Was it as good a fantasy movie as Princess Bride or Stardust? No ... But still it was entertaining enough.
